Announcement PDF ASX ANNOUNCEMENT 30 October 2026 ASX: TSO OTCQX: TSORF FSE: 5D7 31 Cliff Street, Fremantle WA 6011 | +61 8 6383 7883 | info@tesorogold.com.au | tesorogold.com.au QUARTERLY ACTIVITIES REPORT for the period ended 30 September 2026 Tesoro Gold Limited (Tesoro or the Company) (ASX: TSO, OTCQX: TSORF, FSE: 5D7) is pleased to report on activities for the three months ended 30 September 2026 (Quarter). Tesoro’s September Quarter culminated in delivery of major milestones at the El Zorro Gold Project (El Zorro or the Project), with completion of the Ternera resource-definition drilling programme enabling a material increase in confidence level of the Project’s Mineral Resource Estimate (MRE) and subsequent declaration of a maiden 1.28Moz Ore Reserve1 for the Ternera Gold Deposit (Ternera). The updated MRE increased the Measured and Indicated component to approximately 1.47Moz of gold, representing approximately 80% of total contained gold within the pit-constrained MRE, providing the higher-confidence Mineral Resource base required to support the subsequent Ore Reserve. The maiden Ore Reserve is contained entirely within a single open pit and supports a project production life of more than 13 years at the planned 3.0Mtpa processing rate. In parallel, Tesoro continued to progress the Definitive Feasibility Study (DFS) and broader development-readiness activities across mining, processing, tailings, infrastructure, environmental approvals, project execution and financing. With the resource-definition programme complete, drilling also transitioned towards opportunities for further Mineral Resource growth around Ternera and broader new discoveries across El Zorro. HIGHLIGHTS FROM THE QUARTER  Ternera MRE upgraded to 51.6Mt at 1.10g/t Au for 1.82Moz2 , reported at a 0.30g/t Au cut- off grade and constrained within a US$3,500/oz optimised open-pit shell.  Approximately 1.47Moz, representing approximately 80% of total contained gold, classified as Measured and Indicated, an increase of approximately 348koz compared with the August 2025 MRE, including a 95koz Measured Mineral Resource defined for the first time.  The updated MRE followed completion of the 80 hole, 27,162m Ternera infill drilling programme, with final assays received during the Quarter and incorporated into the updated model.  Maiden Ore Reserve of 42.8Mt at 0.93g/t Au for 1.28Moz declared, comprising 93koz Proved and 1.190Moz Probable Ore Reserves, contained entirely within a single open pit.  The maiden Ore Reserve represents approximately 87% of the 1.47Moz of gold within the Measured and Indicated Mineral Resource and supports a 13+ year project production 1 See ASX Announcement released on 18 September 2026: Maiden 1.28Moz Ore Reserve at Ternera – title correction 2 See ASX Announcement released on 27 August 2026: Upgrade to Ternera 1.8Moz Mineral Resource ASX Announcement 30 October 2026 Tesoro Gold 2 life at the planned 3.0Mtpa processing rate.  PFS-level Modifying Factor work supporting the Ore Reserve further advanced the technical basis for the DFS, alongside continued progress across mining, processing, tailings, infrastructure, environmental approvals, project execution and financing workstreams.  Environmental baseline fieldwork was completed during the Quarter, with the Environmental Impact Assessement (EIA) and Sectorial Permit documentation continuing to progress.  Following completion of the infill programme, drilling shifted towards near-deposit Mineral Resource growth and broader discovery targets, with drilling initially focussed to extensional targets around Ternera.  Quarter-end net cash and cash equivalents of A$9.28 million.

ASX Announcement 30 October 2026 Tesoro Gold 3 EL ZORRO GOLD PROJECT El Zorro is located in Chile’s Coastal Cordillera and hosts the Ternera Gold Deposit. Ternera is being rapidly advanced towards development through DFS-level technical studies, permitting and project planning in parallel with ongoing exploration. Tesoro’s 95%-owned Chilean subsidiary, Tesoro Mining Chile SpA, currently holds 94.54% of El Zorro. During the Quarter, activities at Ternera flowed from the completion of resource-definition drilling through an upgraded MRE to enable the calculation of a maiden Ore Reserve. At the same time, the Company continued to advance the broader technical and development workstreams required to define the proposed development configuration and advance technical studies. UPDATED TERNERA MINERAL RESOURCE ESTIMATE On 27 August 2026, Tesoro reported an updated MRE for Ternera of 51.6Mt at 1.10g/t Au for 1.82Moz of contained gold, reported at a 0.30g/t Au cut-off grade and constrained within a US$3,500/oz optimised open-pit shell. The key outcome of the update was the substantial increase in confidence within the Mineral Resource. Measured and Indicated Mineral Resources now total 40.3Mt containing approximately 1.47Moz of gold, representing approximately 78% of pit-constrained Mineral Resource tonnes and approximately 80% of contained gold. This represents an increase of approximately 348koz in Measured and Indicated contained gold compared with the August 2025 MRE and includes a 95koz Measured Mineral Resource defined for the first time.

MAIDEN TERNERA ORE RESERVE On 18 September 2026, Tesoro declared a maiden Ore Reserve for Ternera of 42.8Mt at 0.93g/t Au for 1.28Moz of contained gold, contained entirely within a single open pit. ASX Announcement 30 October 2026 Tesoro Gold 6 Table 2: Ternera Maiden Ore Reserve CLASSIFICATION TONNES AU GRADE CONTAINED GOLD Proved 2.8Mt 1.05g/t 93koz Probable 40.1Mt 0.92g/t 1,190koz Total 42.8Mt 0.93g/t 1,283koz Note: Ore Reserves are reported above an economic cut-off grade of 0.30g/t Au. Totals may not add up due to rounding. The Ore Reserve includes only Measured and Indicated Mineral Resources, with no Inferred Mineral Resources included. It represents approximately 87% of the 1.47Moz of gold contained within the Measured and Indicated components of the August 2026 MRE, demonstrating a high level of conversion following application of the relevant Modifying Factors. The Reserve pit was designed based on a pit shell selected from optimisation using a US$3,000/oz gold price and supports a project production life of more than 13 years at the planned 3.0Mtpa processing rate. The Ore Reserve is underpinned by PFS-level mine designs, schedules and Modifying Factors informed by work across mining, geotechnical, metallurgy, processing, infrastructure, environmental and cost workstreams. This work provides the technical foundation from which the DFS can further refine the proposed mine design, processing configuration, infrastructure requirements, economics and execution strategy. The maiden Ore Reserve represents an important progression in the definition of Ternera, establishing the first mineable inventory for the Project and providing a more defined technical basis for DFS-level mine planning and optimisation.

Development work undertaken during the Quarter included advancement of process design and engineering for the proposed 3.0Mtpa processing plant, mine design and scheduling, engineering for the proposed dry-stack tailings storage facility, power and water infrastructure planning and project execution activities. Tesoro also continued to progress the proposed grid power connection and its project financing strategy. The PFS-level work completed to support the maiden Ore Reserve materially advanced a number of these workstreams and provides the technical foundation from which the DFS can further refine the proposed mine design, processing configuration, infrastructure requirements, economics and execution strategy. The DFS remains targeted for completion during CY2026. Environmental and Permitting Environmental and permitting work continued in parallel with the engineering programme. Environmental baseline fieldwork was completed during the Quarter, with reporting and preparation of the relevant environmental and Sectorial Permit documentation continuing as part of the Project’s permitting pathway. ASX Announcement 30 October 2026 Tesoro Gold 9 EXPLORATION AND MINERAL RESOURCE GROWTH Completion of the Ternera infill programme allowed Tesoro to redirect drilling from Resource definition towards potential Mineral Resource extensions and newdiscovery opportunities. Drilling was initially redeployed to near-deposit targets around Ternera, including holes designed to test extensions to the existing mineralised system. This work provides the potential to add to the Mineral Resource beyond the area supporting the current Ore Reserve while the existing development case continues to be advanced. In parallel, Tesoro continued to progress its new-discovery programme across high-priority targets within El Zorro, with geological, geophysical and geochemical information being used to refine and prioritise the next phase of regional drilling. ASX Announcement 30 October 2026 Tesoro Gold 10 CORPORATE During the Quarter, Tesoro continued its investor engagement programme in parallel with the advancement of El Zorro, attending and presenting at the Noosa Mining Conference, Precious Metals Summit in Beaver Creek, and the Denver Gold Group Mining Forum Americas.
